Because it lowers the threshold for a total informational compromise attack from "exfiltrate 34PB of data from secure govt infrastructure" down to "exfiltrate 100KB of key material". You can get that out over a few days just by pulsing any LED visible from outside an air-gapped facility.

There are all sorts of crazy ways of getting data out of even air-gapped machines, providing you are willing to accept extremely low data rates to overcome attenuation. Even with million-to-one signal-to-noise ratio, you can get significant amounts of key data out in a few weeks.

Jiggling disk heads, modulating fan rates, increasing and decreasing power draw... all are potential information leaks.

Chelsea Manning apparently did it by walking in and out of the facility with a CD marked 'Lady Gaga'. Repeatedly
